A Las Vegas woman, her brother and her adopted son have all been charged with attempting to kill the woman’s husband so as to cash in on a life insurance policy.

Amy Pearson, 42, was also involved in a romantic relationship with her adopted son, 21-year-old Michael Bessey, a police report released Monday stated, and had nearly finalized a divorce with Robert Bessey, 49.

Once the divorce was completed, Pearson would no longer have a legal claim to the $250,000 life insurance policy, the police report said.

On Nov. 14, Robert Bessey was driving his car on Interstate 15 when a gold SUV pulled up next to him and one of the occupants shot him in the neck. Bessey survived the attempt on his life, however, and called 911 with his cellphone.

Surveillence video at a gas station placed Michael Bessey and Richard Pearson, 39, in the van shortly before the crime occurred.

“Michael and Amy were very close,” Robert Bessey told police, the Las Vegas Review Journal reported. Apparently, that closeness was a factor in the divorce proceedings.

Police initially didn’t arrest Amy Pearson, but on the strength of monitored communication between the woman and her adopted son, they built a case against her.

Michael Bessey sent a letter to Pearson shortly after his arrest, and pleaded for his father to drop the charges against him.

A jailhouse confession made to Michael Bessey’s cellmate also helped police zero in on Pearson.

“He and Amy Pearson were to receive $400,000 in total benefits,” the police report stated. “He was going to buy a truck, his mother was going to pay off her mortgage, and the two would never have to work again.”

Interviewed by police, Amy Pearson’s sister-in-law recounted how Pearson lamented turning to the younger Bessey to kill his adopted father.

“That’s what happens when you send a boy to do [a] woman’s work,” Pearson was reported to have said, according to the police report.

There are speculations that Amy Pearson is actually the biological mother of Michael Bessey; he’s the victims stepson after Robert Bessey formally adopted him when he was younger.
